E. ERICSSON, F CHICAGO, ILLINOS SOAP HOLDER rota msi-:WASHING MACHINESApplication filed October 4, 1929. Serial No. 397,200.

My invention is concerned with soap holdersy for dish washingmachines,'etc., and is designed to produce a holder in which a cake ofvhard soap can be placed and hot water run-therethrough as it passes tothe spraying mechanism, so that hot soap-suds will be sprayed upon thedishes or other articles to be washed.

To illustrate my invention, I annex hereto a sheet' of drawings in whichthe same reference characters are used to designate identical parts inall the gures, of which,-

"The soap holder `herein shown and described is employed in connectionwith dishwashing machines of the type shown in my l'prior applicationsNos. 299,486, led August 14, 1928; 317,176, filed November 5, 1928, and

323,876,1iled December 5, 1928, now Patents A Nos. 1,7 98,425, 1,798,426and 1,798,428, dated- March 31, 1931 of which Vapplications the presentapplication may be considered asa quasi-division, since the specificsoap holder herein shown and described is not claimed specifically inthe foregoing applications,but

only in combination with the dish-washing mechanism therein shown.

In Figs. 1 and 2, 10 represents the back portion of a kitchen sink withwhich my dishwashing mechanisms are ordinarily employed, and 11represents the customary hot and cold water mixer, which is providedwith piping 12 leading tothe soap holder 13 which is the subject matterof the present application. As in some forms of my dish Washers it isdesirable to lift the dish-washing mechanism bodily out of the sink, VIhave shown the soap holder as having the supply pipe 14 connected by theswivel joint'l with the piping 12 heretofore referred to. The principalportion of the soap-holder mechanism proper consists of thegenerally-rectangular casing 13, which may take the form of acastingwith which the pipe 14 is integral, andwliich opens into the topofthe casing 13 throughl the aperture 16. The generally-rectangularcasing 13 is provided'on its under side with the elongated outletaperture 17 a which opens into the tubular spraying member 18, which Yisprovided on its under surface with the perforCs-e Tlf WALnEivIAaL.LINDGREN, oF WAUKnc-AN, ILLINOIS, AssIGNoR or ONE-HALF ro ooi-IN frations 19 through which the water is sprayed upon the dishes or otherarticles to be washed passing beneath or above the member, as the f casemay be.' One end of' the casing 13 is provided with the rectangularopening 2O into which fits the end of the soap holder proper, which ispreferably'formed of sheet metal and is rectangular in cross section and'of a size to substantially fill the rectangular hollow in the casing13. This holder 21 is provided with perforations 22 extending along theangle in the top and bottom portions, and with similar perforatons 23extending along the edges of thev side portions, so thatV water enteringthe inlet Vport 16 will-'be compelled to spread out over substantiallythe entire surface of the cake of soapv 24 which will be placed therein,This holder 21 is secured to the cover'or cap 25, which has theoverhanging flanges 26 between which and the Aflange 27 formed on theadjacent end of the holder 13 is interposed the-rubber gasket 28 bywhich the closure is made water-tight.` As ya convenient means vofclamping this endorca-p piece 25 in place, I employ the yoke piece g 29,which has the inwardly-projecting flanges 30 and31 at itsendSco-operating with the adjacent surfaces of `the vflange 27 Theflange 30 is preferably pivotally connected'to the ange 27 by thescrew32, and the set"V screw 33 is threaded through the center oftheyokev 29, so that when the holderwiththe cake of soap is Vputin .placeand the yoke is swung around to .the position shown, thev parts can besecurely clampedtogether byk turning the set VScrew 33.l The operationof the apparatus will be apparent, as the hot water flowing from themixer will perforcebe compelled to flowV all around the cake of soap 24in reachingthe outlet 17 Pand the sprayer 18, so -that thefvvatersprayedon the dishes will be adequately provided with soap to form a suds.

At the same time, it will be noted that the stream of water flowing fromthe pipe 14 through the opening 16 does not strike the cake 24 of soapdirectly, but is deflected and spread out by the adjacent imperforatepart of the holder 2l, so that when it finally reaches the soap throughthe perforations 22 and 23, it has no material velocity, and does nottend to wash the soap away, but merely to dissolve it, so that whilesuliicient soap is dissolved to make the vdesired suds, it isnot wasted,as I have found it will be if the water from the opening 16 is projecteddirectly on thecake of soap.` Y

While I have herein shown and Vdescribed f my invention as embodied inthe form which 'Y from said opening and with said imperforatev .60*

I` at present consider best adapted to carry out its purposes, it willbe understood that it is capable of modifications and that I do notdesire to be limited in the interpretation of the following claimsexcept as may be necessitated by the state of the prior art.

What I claimvas new, and desire to secure by Letters Patent of theUnited States, is:

l. In a device of thefclass described, the combination with a castinghaving a hollow rectangular central portion with one end openv and asupply-pipe portion opening into the center of one side and a spray-pipeportion opening into and extending beyond the ends of the opposite side,of a removable cover for said open end having a.generally-rectanguiarsoap-holder secured thereto substantially fillh ing said hollow portionand having perforations in its sides only adjacent the angles formedthereby and not in the portion facing the supplyV pipe, and means fordetachably clamping said cover in place.

2.1In a device of the class described, a soap distributingmechanismconsisting of a flattened rectangular casing having a water supply'tubeopening inthe center of one ofits larger sides and a perforated rspraytube connected with the opposite side thereof, said casing having anopening in one end, a closure for said openinga rectangular perforatedsoap holder substantially co-extensive in lengthl with the interior ofsaid casing open atl one endl and attached Yat its other end to saidclosure and removable therewith, said soap holder being so constructedthat oneV of its sides has an imperforate area of substantial extent,said soap holder being arranged V within said casing in spaced relationto the walls of said casing with its open end adjacent the end of saidcasing which is remote area adjacent said vrfater supply opening, saidclosure being provided with a flange engaging the casing aroundr saidopening, means for holding said -fla'nge-in'water-tight engagementWithvsaid casing, comprising a yoke Vpivoted at one endto said casing,and aV screw threaded through the yoke and engaging said closure toclamp said flange against said casing.

8. In a device of the class described, a soap distributing mechanismconsistingV of a rectangular casing having a water supply tube openingin the center of one of its sides and a perforated spray tube connectedwith the opposite side thereof, said casing having an opening inone end,a closure-for said opening, a rectangular perforated soap holdersubstantially co-eXtensive in length with the interior of said casingopen at one end and attached at its other end to said closure andremovable therewith, said soap holder being so constructed'that oneofits sides has an imperforate area of substantial extent, said soapholder being arranged ywithin said casing in spaced relation to thewalls thereof with its open end adjacent the end thereof which is remotefrom said opening and with said imperforate area adjacent said watersupply opening, said closure being adapted to make a water-tightengagement with said opening, and readily detachable means for holdingsaid closure in water-tight engagement with said casing.

4. .In a device of the class described, a soap distributing mechanismconsisting ofa casing rectangular in cross section having a water supplytube opening in the center of one of its sides and a perforated spraymember connected with the opposite side thereof, said casing having anopening in one end, a closure for said opening, a perforated soap holderrectangular 1n cross section substan,

remote from saidy opening and with said imfV perforate area adjacentsaid water supply opening, said closure being adapted to make awater-tight engagement with said opening, and readily detachable meansfor holding said closure in water-tightgengagemen't with said casing.

In witness whereof, I haveA hereunto set.
